你好，我正在使用 Andre Miede 的 classicthesis 模板，可以从以下位置下载这里。一切顺利，但在尝试包含 Tikz 图形时，我遇到了意外错误。此错误指出：
! Argument of \language@active@arg> has an extra }.
<inserted text>
\par
l.128 \draw [arrows=<->, shorten >=3.5pt]
(3.5,2) arc (0:45:1.5) node[midway...
I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
我尝试使用scrreprt类并调用classicthesis包在不同的文档中编译这个 Tikz 图形，但它在没有任何警告的情况下显示了该图形。
Tikz 图形的代码是：
\begin{tikzpicture}
\draw[thick, rounded corners=8pt] (1.74,1.5)-- (1.75, 2) --
(2,2.5)--(2.25,2)--(2.25,1.5);
\draw[thick] (1.5,1.5)-- (2.5,1.5);
\fill[pattern=north east lines] (1.5,1) rectangle (2.5,1.5);
\draw[arrows=->,very thick,black] (0,0) -- (5,0) node[right] {$x$};
\draw[arrows=->,very thick,black] (0,0) -- (0,5) node[left] {$y$};
\draw[-,black] (2,2) -- (4,2);
\draw [thick, double distance=1.5mm] (2,2)--(4,4);
\filldraw [thick, fill=white] (2,2) circle (5pt) node[below,left,xshift=-0.2cm] {$A$};
\fill[thick, black] (2,2) circle (2pt);
\filldraw [thick, fill=white] (4,4) circle (5pt) node[above,right,yshift=0.3cm] {$B$};
\fill[thick, black] (4,4)circle (2pt);
\draw [arrows=<->, shorten >=3.5pt] (3.5,2) arc (0:45:1.5) node[midway,fill=white] {$\theta$};
\end{tikzpicture}
我classicthesis-config在调用classicthesis包后在 texfile 中添加了以下几行
\usepackage{tikz}
\usetikzlibrary{patterns}
\usetikzlibrary{arrows}
有人知道是什么原因导致了这种行为，或者知道如何修复它吗？抱歉没有发布 MWE，但需要下载整个模板。
编辑调用 tikz 库babel我可以编译我的图形，但是当我尝试使用 subfig 包选项将其放入图形环境中时会出现相同的错误。
这是图中的代码，顺便说一下，这在另一个文档中编译成功，我也在使用\usepackage{subfig}
